MSDS
Material Safety Data Sheet
• properties of a particular substance
• procedures for handling, storing, disposing
or working with that substance in a safe
manner
• physical data (melting point, boiling point,
flash point, etc.), toxicity, health effects,
first aid, reactivity,
• format of an MSDS can vary from source
to source (click here for an example)
MSDS – where do you find them?
• Every chemical supplier (Sigma, Spectrum) must provide
an MSDS for each product.
• Consumers can see a copy of MSDS if one knows the
compound’s name.
• Available online
www.chemistry.pomona.edu has a link to “moldata” and
